Function changeDistributor

changeDistributor(distributorName: string, copyCfgnValues?: boolean): Promise<void>
Change the current configuration to the given distributor or the company (if left empty).
Note: Although there's a seamless transition to the distributor it should be used sparingly, as it creates new configurations in the background.

Example
```
CfgrUtils.onBeforeCheckout(async () => {
  if (country === 'AT') {
    await CfgrUtils.changeDistributor('distributorAT');
  }
});
```
Parameters
- distributorName: string
  
  name of the distributor to switch to, or null to switch to company
- copyCfgnValues: boolean = true
  
  true to copy all cfgn values (input), false to use an empty cfgn
Returns Promise<void>
